In addition to these underpinnings, it also introduces a powerful and innovative graphic user interface — later also used for the tablet computer iPad. These machines, of course, did not have an operating system.
Although it was not a commercial success and Xerox abandoned the project, it was pivotal in the history of computer systems since it integrated the mouse, ethernet networking, a bitmapped video display, and a detachable key.
